French Toast Overview

French toast is made by soaking bread in an egg-and-milk mixture and cooking it on a griddle, often topped with syrup or powdered sugar. Despite the added protein from eggs, the base ingredient is bread, making French toast high in carbohydrates and unsuitable for low-carb, keto, or diabetic-friendly eating in typical portions.
